S.E.P Vertical External Risers are manufactured from Grade 304 Stainless steel. Flat sections are machine welded prior to the wall & support sections being Tig welded by hand. Lastly where required the joints are bead blasted to clean the welds.

This process gives our risers strength with a quality finish.
